You have the uneviable square room dimensions which is a tough hurdle to overcome. Look to highly adjustable speakers like VMPS which allow you to tailor the sound via tweeter, midrange, and bass adjusting to get the best sound in YOUR room, not just the store. Whatever you decide, if you're having a hard time getting the sound from your system you'd like, try having your system oriented so it's shooting diagonally from one corner towards the opposite corner. Jim Smith, the sound guru who sets up systems for shows and people's own home systems, has that tip especially for near square rooms. Specifically, the VMPS RM30, 626R, or the RM-2 would give you tremendous dynamics, clarity and transparency throughout all frequencies, bass that will massage your colon, and ADJUSTABILITY to get the best sound in your room. Good luck, Bob
